mb/lenovo/*/acpi/superio.asl: Replace with GPLv2+ equivalent

Replace functionally identical files with t440p/acpi/superio.asl which
is licensed under more flexible terms (GPL-2.0-only or no licensing
terms vs. GPL-2.0-or-later). Apart from licensing terms these files are
identical.

This makes diff between boards smaller.
